bishop Roger's work incorporated in the towers,
taken together with another Transitional bay at the east end, make it
possible to imagine the whole interior of what must have been the most
remarkable nave in England. It was unusually broad. From the ground to
the first string (about 16 feet) there was plain wall. Above this was a
triforium (if it can be so called[57]) of the unusual height of about 28
feet, and there were thus no windows except in the clearstorey, and
there only in alternate bays. According to Sir Gilbert Scott the
triforium and clearstorey were probably continued across the west wall.
The bays were alternately broad and narrow, and there is room for five
of each sort. The westernmost bay shows in the triforium stage a round
arch comprising four pointed arches. Of these the two in the middle are
raised above the others on shafts of two stages, in the upper of which
the capital is circular and its moulding is continued along the tympanum
to the _apices_ of the two lower arches. The tympanum is relieved by a
sunk quatrefoil in a serrated circle, and so is the space under either
of the two central sub-arches. The passage in this bay has been built
up, and the bay itself shortened, probably when the tower arches were
made.

In the adjoining narrow bay, the comprising arch is pointed, there are
only two sub-arches, and there are no quatrefoils, except in the
tympanum on the north side. Doors have also been inserted in this bay to
communicate with the passages behind the arcades in the towers.

The shafts throughout are single, and (in the sub-arches) detached, and
the details generally are the same as in all Archbishop Roger's work. It
is worthy of remark that the tympanum over the sub-arches is flush with
the lower part of the wall, and that the comprising arches, with all the
walling above them, are a plane in advance. The more natural plan would
have been to make the comprising arch flush with the wall below, and to
have set back the sub-arches and tympanum. In consequence of Archbishop
Roger's arrangement the shafts of the comprising arch stand, not upon
the sill of the triforium, but upon corbels, each of which carries two
of them and also a roof-shaft[58] which forms with them a cluster.

The clearstorey shows in the broad bay a stilted round arch,
